Core Performance And Dfferentiated Performance
1. Ultimate Water Resistance (Core): Permeability coefficient ≤ 1.0 × 10⁻¹³ cm/s. The dense molecular structure of HDPE can prevent water, sewage, and chemical liquids, far exceeding that of ordinary geotextiles or PVC membranes. It is suitable for strict waterproofing scenarios such as landfill sites, eliminating leakage pollution.
2. Super Durability (Core): Resists UV radiation for 500 hours while maintaining 80% tensile strength. Resistant to acids and alkalis (pH 2 - 13) and does not crack at - 40℃. Service life is 20 - 50 years, 30% more durable than LDPE membranes, significantly reducing long-term maintenance costs.
3. High Adaptability Mechanical Properties (Core): Tensile strength ≥ 23 MPa, elongation at break ≥ 700%. Can adapt to foundation settlement; puncture resistance ≥ 300N, can withstand sharp objects during construction, more suitable for complex terrain laying than composite geotextiles.
4. Efficient Construction (Differentiation): Width can reach 4 - 8m, fewer seams, and hot-melt welding (180 - 220℃) is easy to operate. Construction efficiency is 25% higher than EVA membranes, especially suitable for rapid advancement of large-scale projects.
5. High Cost-effectiveness (Differentiation): Unit area cost is only 60% of TPO waterproofing membranes, yet it has a longer lifespan and lower maintenance costs. In medium and large-scale water conservancy and environmental protection projects, the overall cost advantage is significant.
Application Scenarios And Cases
1. Leachate prevention for landfill sites: Applied to the bottom and the covering layer of the landfill, it prevents the leakage of leachate from polluting groundwater. For example, in a landfill site in Jinan, Shandong Province, after the change, the groundwater COD met the standards within 3 years, and the vegetation coverage reached 85%.
2. Artificial lake landscape project: Adapted to complex terrains such as mountains, it prevents water seepage and leakage. The landscape lake of a pumped storage power station used it for seepage prevention, with no loss of 4500 cubic meters of water storage volume, and it was suitable for spillway facilities.
3. Livestock farm manure treatment: As the main material for black membrane septic tanks, it prevents seepage and promotes anaerobic fermentation to produce biogas. It is suitable for the "water bubble manure" treatment of large pig farms, achieving zero discharge of manure and energy recovery.
4. Isolation of chemical wastewater tanks: Resistant to acid and alkali (pH 2-13) corrosion, it prevents the leakage of toxic waste liquids. It is used for seepage prevention of liquid storage tanks in chemical plants, resisting chemical erosion and ensuring soil safety.
5. Water conservancy channel seepage prevention: Reduces water loss during transportation, suitable for uneven terrain of the channels. It is laid on agricultural irrigation channels to improve water transmission efficiency and contribute to water-saving agriculture.
6. Hazardous waste disposal site: Isolates harmful substances such as heavy metals. Applied in a disposal site in Xinjiang, it solved the leakage problem and the soil quality reached the safety standard.
The Future Development Trend Of The Market
1. Market size and growth momentum: By 2025, the market size in China is expected to exceed 18 billion yuan, with a compound annual growth rate of 12%-15%. The core driving forces come from stricter environmental policies and increased infrastructure investment. The demand in three major fields - landfill sites, water conservancy projects, and mine restoration - accounts for over 70%. The major water conservancy projects in the 14th Five-Year Plan directly drive a demand increase of 250,000 tons.
2. Competitive landscape and industry concentration: The industry shows a trend of concentrated leadership, with the market share of the top five manufacturers rising from 48% in 2019 to 62% in 2023.
